Destructuring assignment
الأهمية: 5
We have an object:
let user = {
name: "John",
years: 30
};
Write the destructuring assignment that reads:
name
property into the variablename
.years
property into the variableage
.isAdmin
property into the variableisAdmin
(false, if no such property)
Here’s an example of the values after your assignment:
let user = { name: "John", years: 30 };
// your code to the left side:
// ... = user
alert( name ); // John
alert( age ); // 30
alert( isAdmin ); // false
let user = {
name: "John",
years: 30
};
let {name, years: age, isAdmin = false} = user;
alert( name ); // John
alert( age ); // 30
alert( isAdmin ); // false
